Prime Minister Justin Trudeau and the new Liberal government face a unusual dilemma. They have an ambitious legislative agenda. They have a majority in the House of Commons. But they do not control the Upper House, the Senate. In that legislative chamber, the Conservative Party have 47 members. The Liberals cast their senators, now numbering 29, from their caucus. There are 7 independent senators. And 22 vacancies. Because the Liberal senators are no longer subject to party discipline, their votes cannot be controlled. One can imagine nevertheless that Liberal senators would be inclined to vote for the Liberal Party’s legislative agenda. But the Conservative Party Senators, however, have been strictly whipped, at least under the leadership of former Prime Minister Stephen Harper.
